gdk: Generate crossing events around touch devices' press/release Anytime a touch device interacts, the crossing events generation will change to a touch mode where only events with mode GDK_CROSSING_TOUCH_BEGIN/END are handled, and those are sent around touch begin/end. Those are virtual as the master device may still stay on the window. Whenever there is a switch of slave device (the user starts using another non-touch device), a crossing event with mode GDK_CROSSING_DEVICE_SWITCH may generated if needed, and the normal crossing event handling is resumed.

gdk: Allow display subclasses to override the type used for windows We want to have different window types for different displays, so we can write code like this: #if GDK_WINDOWING_X11 if (GDK_IS_X11_WINDOW (window)) { /* do x11 stuff */ } else #endif #if GDK_WINDOWING_WAYLAND if (GDK_IS_WAYLAND_WINDOW (window)) { /* do wayland stuff */ } else #endif { /* do stuff for unsupported system */ } This requires different GdkWindow types and we currently don't have that, as only the GdkWindowImpl differs. With this method, every backend defines a custom type that's just a simple subclass of GdkWindow. This way GdkWindow behaves like all the other types (visuals, screens, displays) and we can write code like the above.
